直立防波堤振动──滑移运动分析的模型和方法

A model for analysis of vibration - sliding motionof upright breakwater

建立了一个动力系统模型及相应分析方法，对破碎波冲击作用下直立式防波堤的振动—滑移运动过程进行数值模拟，预测特殊波浪力作用下防波堤可能出现的滑移量。用本文模型和方法对一沉箱防波堤在破碎波作用下的运动过程进行了计算，并分析了沿基床顶面的滑移对沉箱位移、摇摆角、滑移力和倾覆力矩的影响。

── A dynamic model and the approach , which can be used to simulate the vibration-sliding motion of upright breakwater subjected by breaking wave impact , are developed. The sliding distance of breakwater under exceptional water can be estimated. The vibration-sliding motion process of a caisson breakwater is simulated by the model , and the effects of the caisson slide on the displacement . rotation , sliding force , and overturning moment are investigated.
